SMOKE-CONSUMER.

SPECIFICATION forming part of Letters Patent N 0. 404,775, dated June 4, 1889.

Application filed March 18, 1889. Serial No. 803,692. No model.)

To all whom it may concern:

Be it known that I, JAMES OLEMEnT BUT- LER, of Quincy, in the county of Adams and State of Illinois, have invented anew and useful Improvement in Smoke-Consumers, of which the following is a specification.

My invention consists in a new and improved smoke-consumer, which will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a front view of the furnace to which my invention is shown as applied. Fig. 2 is a side elevation with parts of the furnace broken away. Fig. 3 is a sectional yiew taken on the plane indicated by line :20 as of Fig. 2; and Figs. 4 and 5 are detail views, which will be hereinafter referred to.

The same letters of reference indicate corresponding parts in all the figures.

In the accompanying drawings I have shown my invention applied to a sta ionary steamboiler furnace.

Referring to the several parts by letter, A indicates a steam-boiler, and A the dome of the same. 13 indicates the front of the furnace; O, the grate; and D the bridge-wall, which will be hereinafter more particularly referred to. Beneath the boiler are arranged in the bridge-wall three tile fines E, that being the number used in the boiler here illustrated. These tile fines E are each ten inches in diameter at their front ends and taper to nine inches diameter at their rear ends, and are each thirty-two inches long, said flues to be increased or diminished in size according to the size of the boiler and the space required in the furnace.

F indicates the main pipe, which passes through the bridge-wall below the grate, and which consists of a hollow tube or pipe two inches in diameter, (the size of this and the other pipes hereinafter described varying according to the service required.) Upon the outer end of this main pipe, which extends out beyond the bridge-wall under the grate, as shown, is screwed or otherwise secured a cap G, which is formed with a central aperture G, three-eighths of an inch in diameter, and a series of smaller apertures G to admit air into the pipe, and arranged, preferably, in a circle around. the central aperture.

The main pipe F passes entirely through the bridge wall below the grate, and at its rear end is connected by the T with the auxiliary or branch pipes H H. These branch pipes are one-and-one-fourth inch in diame'ter andextend up back of the bridge-wall, and thefi forward through the bridge-wall on a line with the center of the tile fines E, as most clearly shown in Fig. 3 of the drawings.

A steam-pipel leads from thedome of the boiler down in front of the furnace to a point below the grate C,where it passes through the front of the furnace, and its lower end 1 enters the front end of the main air-pipe F through the central aperture G of the cap G. The end I of the steam-pipe extends from three to five inches within the front end of the main air-pipe, and is reduced in size, as shown in the drawings, tapering from threeeighths to three-sixteenths of an inch in diameter, thus acting as an injector, injecting and forcing the air into the furnace.

It will be seen that the current of steam brought through the pipe I from the dome of the boiler will force a steady current of air through the pipes into the furnace with the steam, and the steam, after entering the pipes F and H H, will become superheated and is not visible in the furnace, and will cause the combustion to be complete, consuming all the gases which ordinarily pass off in huge volumes of black smoke.

The bridge-wall extends up close around the boiler, as clearlyshown in Fig. 3 of the drawings, and will confine the heat and gases to the fines, thereby bringing the air and superheated steam brought through the pipes F and H H in directcontact with the gases upon entering the furnace. The steam-pipe is provided with valves 1 by means of which the amount of steam flowing through the pipe can be regulated as required.

J indicates a brick floor or way arranged longitudinally below the boiler, inclined downward toward the'fnrnace, as shown in Fi 9 so that its forward end is just below thg in ner end of the tile-fines E, and running back to the soot-pit K.

By reason of the perfect combustion, there is no accumulation of soot to become ignited and burn out stock, therebygreatlydiminishing the danger and liability of fire. This is an important feature.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily understood. It will be seen that while it is comparatively simple and also inexpensive in construction it will cause a perfect combustion of all the gases which would otherwise pass off in huge volumes of black smoke, thus ei'fectin g a most important object, and that by reason of this perfectcombustion there will be no accumula tion of soot to become ignited. The invention can of course be applied to all classes of horizontal boilers.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, with a boiler and the furnace and bridge-wall of the same, of lines leading through the bridge-wall, a main pipe passing through the bridge-wall below the furnace-grate, branch pipes lcadin g from the main pipe up and forward through thebridgewall above the furnace-grate, and a stean1- pipe leading from the l'ioiler-dometo the main pipe.

2. The combination, with a boiler and the furnace and bridge-Wall of the same, of flues leading through the bridge-wall, the main pipe and the branch pipes, the apertured end cap, and the steam-pipe, substantially as set forth.

The combination, with a boiler and the furnace and bridge-wall of the same, of fines leading through the bridge-wall, the main pipe and the branch pipes, the apertured end cap, and the steampipe having the tapering lower end, substantially as set forth.

4. The combination, with a boiler and the furnace ainlbridge-wall of the same, of the tapering flues, the main pipe having the apertured end cap, the branch pipes and the steanrpipe having the tapering lower end, substantially as set forth.

5. The combination, with a boiler and the furnace and bridgewall of the same, of the tapering fines, the inclined floor, the main pipe having the apertured end cap, the branch pipes, and the steam-pipe, si'ihstantially as set forth.
